In my quest for finding an inexpensive source of labels for my small honey harvest, I found onlinelabels.com. I have used this company for years as a label source for the garden center that I work at.
I was pleased to find that they have a label design program that works with all of their label formats and is very easy to use. Labels can be as little as 0.02 each for your own custom design. You just need to print them on your SOHO printer.
This one is specifically called a honey label, but there are dozens of shapes and sizes to choose from. http://www.onlinelabels.com/OL1029.htm
